SUPERHEATERHBOlLER..

To (all, tell/m, it 'muy emiro/77s.-

v Be it known that l, Jona' E. BELL, olv Barberton, Summit county, Ohio, have invented a new and uselul `Superheater-Boiler, of which the following is a full, clear, and exact description, reference being` had to the ac companying drawings, forming part of this specification, in which-A Figure 1 is a diagrammatic. secti iial'i"ioiit elevation showing one forni oi" my iniproved 'superheater boiler; Fig, 2 is a sectional side elevation of-the saine; Figs. 3 and Li are views similar to Figs. i and 2 respectivelyr showing a modified forni; and Figs. and are also views similar to Figs. 1 and 2 showing another arrangenn'nit olv the furnace.

My invention relates to that class ol water tube boilers wherein. two or lmore loiigitudinal mud drums' are connected by water tubes to one or more longitudinal steam and Water drums, the gases passing longitudinally of the drums and .preferablyv being given up and down passes by baliles.

'The object ol the `invention is to combine a su perheater in the structure ot said boilers in an ellieient and econrnnieal manner.

In the drawings referringto the form oi" Figs. land 2, I show one longitudinal steam andwatei" drum 2 connected b v banks ol: tubes 3 to two longitudinal mud drums 1i, 4, 5 is the front wall, 6 the rear wall of the selting, 7 the furnace and S the oli'take liuc, E) is the root' or arch oi the combustion chamber which in this torni is below the boiler,

- the arch extending a portion of the length of the mud drums and having baille exten.- sions 10 which protect the mud drums, While allowing the gases to [low up through the three ports into the rear ot the water tubes 3. All is an iunvardly extending bafiie between the water tubes, and i2 is a 'depending baille at the troni ot the water tubes. i in this lerin i z-how the. superhcater aseonsisting el two banks ol.' superheating tubes i3 which connect the upper compartments Li and of the drum 2 with the compartments iti el." the two drums 4, Li. The

compartments L and i5 are termed by a transverse partition 17 having a hole or opening near .its top above the water level, and a closed. partition i8. The chamber 16 in the lower drun'is are formed b5 complete partitions il) one for each drinn, 2?() the Specification of Letters Patent.

steam outlet. ln this form the gases rise through the liist pass of water tubes, decend through' the second Aass of water tubes and then rise through the last pass among the superheating tubes, to the oll'talre. 'lhe steam passes from the rear part ol2 the drum 2 into the compartment i4, flows down through the two sets of tubes into the chambers 16 and thence rises through other oli the tubes i3 to the chamber i5 whence it is taken oil. 1n Figs. 3 and 4 l show a form similai to Figs. l and 2, except that three mud drums 4 are provided, the ballles 10'l being correln these ligures parts similar to those'ol' Figs. l and 2 are designated by similar numerals with the letter a applied.

ln Figs. 5 and (i l. show loi'ms similar to those ol: Figs. unil 'i, except that the lurnace 7" is external and discharges directly into the lower portion oli the water tubes 3b, above the muil drums. Parts in these ligures similar to those ol Figs. 3 and 4 are i'lesigilated` by similar numerals, with the letter b applied.

The advantages ol" in v invention result lrom the efficient and economical arrangement ot the superheatcr in combination with a boilerot the class speciiioal.

i Many changes may be made in the liorin and arrangement ol' the l'urnace, the drums,

the superheater connections, etc., without' departing from my invention.

l claims l. A water tube boiler having at least two longitudinal mud drums connected by banks oi: tubes to an upper longitudinal steam drum or dinins, means for 'passing gases longitudinally of the drums among the tubes, and a superheater in the boiler setting and having superheating tubes exposed to the gases the boiler havii'igwater tubes located between the source ol" heat and the superheater, substantially as described.

A water tube boiler having at least two longitudinal mud drums connected by water tubes to one or more longitudinal steam and water drums, battles arranged to give the gases up and down passes among the tubes longitudinally oi' the drums, and a superlieater located in tire boiler setting back of the iirst pass, said superheatt.i being exposed IOO ' to the heat oi the gases and connected to the steam space of the boiler; substantially as described.

A Water tube boiler' having at least two longitudinal inud drums connected by Water tubes to one or more longitudinal steaiii and Water drums, baffles arranged to give the gases serial up and down passes-longitudinally ofthe drums and among the water tubes, and a superlieater forming at least 4the major portion of the heating surface in a pass back of the first pass of the gases among the tubes; substantiallyas described.

4. A Water vtube boiler having at least two;

longitudinal mud drums connected by water tubes to one or more longitudinal ,steain and water drums, apart of each of the drums being out oil' bya transverse partition forming steam chambers, and superheai/ing tubes connecting said chambers; substantially as described.

5. A water tube boiler having a plurality 7. A water tube boiler having at least two longitudinal mud drums connected by upright water tubes to one or more upper longitudinal steam-and Water drums, baffles ar-r ranged t'o give the gases up and down passes longitudinally of the drums among the tubes, the drums having transverseI partitions dividing them into water and steam chambers,

the water chambers being located between the source ol heat and the steam chambers, and upright superheatiiig tubes connecting the upper andlower steam ohaiiibers and forming at least a iiiajor part of the heating surface inone pass ol the gases in rear or' the iirst pass, substantially as described.

8. A water tube boiler having twol oi' more longitudinal niud drums connected by upright banks of tubes to an upper longitudinal steam and Water druiii, the steam and Water drum having a partition vdividing it into steam and water chambers, upright superheating tubes connected to the steam Chambers, and means for passing the heat up and down over the tubes in the longitudinal direction 'of the drums; substantially as described.

9; A water tube boiler having a plurality of longitudinal niud drunis connected by water tubes to a longitudinal steam and water drum, baillea arranged to give the gases up and down passesover the tubes and in the longitudinaldirection of the drums, and a superheater in the boiler -setting located in one oi the passes in rear of the lirst pass substantially as described.

ll). A water tube boiler having a plurality ot longitudinal niud drums connected by water tubes to a longitudinal steam andwater drum, balli es arranged to give i' he gases up and down passes oyler the tubes and in the loiigitudinal direction of the drums, ard a superheater in the boiler setting located in one of the passes in rear of the iirst psi-is, said super-v heater forining the inajorpoi 'on of the heating surface in its pass g substantially as described.

In testimony whereofl I have hereunto set niy hand.
